When using Fennec for the first time, I tried to double tap on an empty space on the tab bar, to open a new tab, and this didn't work.

I guess this behavior should be implemented, as it is consistent with the desktop browser (double click on an empty space opens a new tab).

This is a duplicate of bug 563973.
on IRC, Madhava said he did not want to add this feature to the core browser. It's too hidden and could be executed during an accidental double-tap more often than in desktop Firefox.

An add-on could add this behavior if it wanted to.

I don't think we want to do this. Doubletap isn't really a widely used interaction on touch devices other than for zoom - I'm not sure that it's worth using this as a one-off interaction for something where there is a easy and near-at-hand alternative (the button).

For me, holding a tablet, the button isn't near at hand. It's a long reach for my reasonably lengthy thumb. 

Also, I don't care about this on phones and my bug which was duped here was filed against tablets and not phones if that makes a difference in reconsidering the wontfix.

I agree this is worth re-opening because of tablets.

This patch is basically like Vivien's, but it uses "TapDouble" instead of "dblclick" because dblclick is hard to trigger on a touchscreen.  (You have to tap twice in pretty much exactly the same place for dblclick, while TapDouble is more lenient.)

You're right for dblclick in general but in this case it's not really relevant since the tab bar is huge :) But dblclick will probably not fired for some platforms so TapDouble is likely the right approach. The only thing I don't like is using BrowserUI.addTab() directly into tabs.xml, could you use the same mechanism use for reloadtab & co?

This addresses Vivien's comments above.

This also adds a clickcount="1" filter to the main onclick handler, to prevent it from firing at the same time as a TapDouble.  (Without that change, if your double-tap hits an existing tab, then it opens a new tab but selects the old tab.)

So this won't work on the mobile phone, only on tablet?
This patch will actually work on in both the phone and and tablet layouts.
OK. let's land it and see what we think.

Depends on: 692811
Backed out because the Fennecmark Tzoom benchmark breaks with this change:

Filed bug 692811 for fixing Fennecmark.  When that is fixed, we can re-land this patch.

Verified on phone and tablet: when double tapping on an empty space on the tab bar a new tab is opened.

Also when double tapping on an existing tab, a new tab is opened and the tapped tab is selected. Is this a expected, or is it a new issue?
